+## How to configure?
+
+You can configure state, details and git integration by changing Discord Presence LSP settings. This can be done in <kbd>zed: open settings</kbd> with following configuration:
+
+```json

+  "lsp": {
+    "discord_presence": {
+      "initialization_options": {
+        "state": "Working on {filename}",
